RESUMO
Sports-related injuries of the thumb, including fractures and dislocations, are very common. The anatomic basis for these injuries is discussed. Treatment options include functional bracing and early operative intervention, thus hastening a return to sporting activities.

The photochemistry of 4-aminobenzoic acid has been investigated using two validated reversed-phase HPLC methods. Up to nine photoproducts have been detected, with chromatographic evidence for the formation of 4,4'-azobenzenedicarboxylic acid and 4,4'-hydrazobenzenedicarboxylic acid. The synthesis and analytical characterization of 4,4'-hydrazobenzenedicarboxylic acid is reported.

In 1994 the Royal Flying Doctor Service of Australia celebrates its 66th year of service to rural Australians. From an experiment in Cloncurry, Queensland, in 1928, the organisation has grown to become a national aerial health service operating 37 aircraft over approximately 80 per cent of the Australian continent. The development of the RFDS and its current work is woven into the fabric of past and contemporary life in outback Australia.

Listeria monocytogenes survived and, under most conditions, multiplied when inoculated directly into the cheese milk of laboratory made Camembert cheeses. The rate and extent of growth was reduced at lower storage temperatures. Significantly higher rates of growth occurred at the surface compared with the centre of the cheeses, and these were probably associated with increased pH and proteolysis at the cheese surface due to the mould ripening process. Similar results were obtained with Camenbert cheeses surface inoculated after manufacture. There was also temperature-dependent growth of List. monocytogenes on a range of inoculated commercially manufactured soft cheeses. Significant growth occurred in Cambazola, French and English Brie, blue and white Lymeswold, French Camembert and Brie with garlic. Little if any growth occurred in blue and white Stilton, Mycella, Chaume and full fat soft cheese with garlic and herbs at the temperatures examined.

Nebulized bronchodilators are commonly used in the management of patients with airflow obstruction, although there is little information available on the bronchodilator output from the nebulizer unit. We have examined the fluid and salbutamol outputs of a single jet nebulizer from two commercial manufacturers at 1 min intervals up to 12 min. The drug and fluid output continued throughout the study period, with a greater fluid output leading to an increase in the concentration of salbutamol remaining within the nebulizer unit. This suggests that weight change is not a good indicator of drug output. Furthermore, there was a marked difference in peak salbutamol output between the two nebulizer units, being 2.9 mg (55%) with the Micro-Neb unit and 1.98 mg (38.7%) with the System 22 unit.
